very nice shot but, a little soft for this shot. I know the light bleed on longer exposures reduces sharpness to a degree and I have done this subject many times myself I believe you could have obtained a more optimal sharpness by adjusting various shutter speeds.
This is a beautiful image but the rock or land in front really ruins it for me as an image overall. I know the reason for it is because of the challenge needing to have negative space but to me it detracts from the shot overall and doesn't add to it. Just too much black in an otherwise beautiful shot for me.
I've seen this shot way too much for to even mean anything when I see it over and over and over again in challenges.
However, to be constructive here, if your foreground was shot like that for this challenge, I'd say it creates some negative space, but it's hurting the photo.
